A team of University of 蜜桃影像 Fairbanks students will build the Air Force a nanosatellite roughly the size of an ordinary loaf of sliced bread to show that communications technology of large satellites can be packed into a small space and deliver much more data.

蜜桃影像 was the only one out of 10 university teams to advance to the next phase in the University Nanosatellite Program, managed by the Air Force Research Laboratory's Space Vehicles Directorate at Kirtland Air Force Base, New Mexico.

Students presented their work in January in New Mexico to 12 judges representing the Air Force, Space Force and industry.

蜜桃影像 will receive $419,690 to deliver the satellite to the Air Force Research Lab in two years, but the team hopes to be ready in fall of 2025. Funding is provided by the Air Force Office of Scientific Research and the American Institute of Aeronautics and Astronautics.

Students will operate the satellite if it passes a variety of tests and is successfully deployed in space.

鈥淧hase A of the Air Force Research Laboratory鈥檚 University Nanosatellite Program has pushed our students to act like professional engineers,鈥 said Denise Thorsen, 蜜桃影像 engineering professor and director of the 蜜桃影像 Space Grant Program. 鈥淭he AFRL calls us 鈥榮mall but mighty.鈥 That鈥檚 because we do not have the volume of students that other universities have.鈥

Students working on the nanosat project are part of the Space Systems Engineering Program, a collaboration between the 蜜桃影像 College of Engineering and Mines and the 蜜桃影像 Space Grant Program housed in the 蜜桃影像 Geophysical Institute.

The avionics test stack of the students鈥 nanosat project sits in a clean room in the Space Systems Engineering Program Lab at the University of 蜜桃影像 Fairbanks. The avionics stack includes, from bottom to top, the attitude determination and control system, electrical power system and the shared board containing a UHF communications system and the command and data handling systems.

Nanosats, each consisting of one to 24 4-inch cubes, have proliferated in recent years. 蜜桃影像 2,300 had been launched as of 2023, up from fewer than 100 in 2010. That rapid increase means communications technology must improve because available radio spectrum is limited.

In their nanosatellite, the 蜜桃影像 students will test ways to improve satellite information throughput. They will not only put more information in transmissions but also use an antenna that can adjust its signal direction to connect with a ground station.

鈥淲ith a smaller communication system that doesn鈥檛 require costly subsystems to assist it, it is possible to make smaller, cheaper satellites that are still able to transmit a large amount of data,鈥 said Caleb Fronek, a computer science student who is the project鈥檚 program manager and software lead.

In addition to Fronek, the current team includes electrical engineering student Dominique Hinds, the chief engineer and communications lead, and mechanical engineering students Brian Bieshelt and Anthony Melkomukov, who work on the satellite鈥檚 structure and mechanical components and conduct thermal analysis of the satellite.

The project is the culmination of research conducted by four 蜜桃影像 master鈥檚 students going back to 2013.

Thorsen and then-graduate student Justin Long submitted the 蜜桃影像 nanosat proposal in 2021, which included work from Long鈥檚 master鈥檚 thesis, in 2021. Long now works at NASA鈥檚 Goddard Space Flight Center. 

蜜桃影像鈥檚 proposal was accepted into the first phase and received $220,000 for initial work. Two years of research by undergraduate and graduate students ensued, culminating with January鈥檚 presentation and advancement to the next stage.

鈥淏eing the only team selected to advance to the next phase in this highly competitive program is evidence of the dedication and ability of our students,鈥 said Nettie La Belle-Hamer, 蜜桃影像鈥檚 vice chancellor for research. 鈥淚t is a great achievement for them, and they have proved they are up to the challenges of the next phase in this program as well as in their professional lives.鈥

The U.S. military funded the work, but it has broader applications, Fronek said. 鈥淚t can be used on commercial satellites, possibly even adapted to be used on ground-based communications.鈥
